11 claims.

The present invention relates to lining machines` and has particular reference to machines for applying a uniform and even amount of liquidgor semi-liquid lining material to the flanges of cans 5 or can bodies.

An object of the invention is the provision of lining units in a liningv machine which receive a regulated amount of lining material and which by a wiping action evenly distribute the same on the flange of a positioned can.

A further object ofthe invention is the pro- Vision of a lining machine of `the character described which automatically propels cans having flanges to be lined through a lining operation and during such passage applies a liningmaterial on the iianges,` yboth the cans and the units moving continuously but along different paths.

The invention contemplates the-application of a liquid lining material rst to a lining pad and from the lining pad to the flange of a can, the amount of liquid put on the pad being regulated in amount and evenly spread by a Wipingaction onto the surface of the pad and a similar spreading and wiping action isthen utilized to deposit a portion of the lining substanceonto the can flange. I

Another object of the invention is the provision of a lining machine which may be used in connection with a can closing machine by means of which the llange of a can is evenly covered with in connection with the accompanying drawings,

discloses a preferred embodiment thereof.

In the preferred embodiment ofvthejpresent invention as disclosed in the drawings a rotating spider carries the lining pads which are supplied With a liquid or semi-liquid lining material. The charge of this liquid is applied to the n pads at each cycle of operation and this appli- 5 cation is made by a rotating roller located in the liquid. The lining pads also rotate on their own axes and in so doing produce a wiping action relative to the applying roller. 'Ihe lining padswith their supporting spider are Vadjustable for 10 different heights of cans to be lined.

Each lining pad is carried'around in a circular` path of travelby the spider and at one place is brought in alignment with the can body which is being conveyed continuously through the ap-` paratus. A portion of the can path coincides with the path of the lining pad to effect such alignment and at such a time and during the uninterrupted advancement of both can and pad the latter descends and with a wiping action caused by the constant rotation of the pad about, its own center delivers a film of lining material on the top flange of the can below. The pad is then raised and the can body is conveyed from: the lining apparatus. 25

The lined can is now in condition for attachment to a can end'or cover and may be immediately conveyed into a double seaming machine such an association being disclosed in the drawings. The term can is used in its broad sense and designates either a can having a bottom or only a. can body, either of these being lined in the sameV identical manner. f

The lining pads and their supporting spider are carried in a frame II (Figs. 1 and 2) which may be a part vof or Which may be closely associated with a double seamer generally indicated by theA numeral I2. In the drawings the framer II is shown as being bolted at I3 directly to the double seamer and this frame II is also indirectly `sup-v ported on a column I4 which provides a more rigid structure. l

The lining pads, indicated generally by the numeral I5, are carried on the lower ends of Ver- Each shaft is carried by the` spider which is indicated by the numeral I 1 and this spider is carried by the frame II. as will be hereinafter more fully described. Cans or`v can bodies 2| to be lined are introduced into. the machine (Figs. 1 and 2) and each can is formed with a flange 22 at the top and these cans or can bodiesare 4continuously advanced. from the time they are first introduced into the; machine until they pass into the doublei seamer I2. 3

The cans 2| are brought into the machine in any suitable manner as by conveyor chains which operate in a can feed table 26 carried on the frame Il. Each chain 25 at the machine end operates over an idler sprocket 21 (Figs. 4 and 6) and is moved in any suitable manner. Each sprocket 21 rotates over a horizontally disposed shouldered stud 28 which is threadedly secured in a vertical wall of the feed table 26.

The cans 2I`ride on and are carried 'forward by the upper runs of the chains 25 and at such time are retained ina straight line of travel by guide bars 29, 3| (Figs. 1 and 2)f carried on brackets 32 mounted on the feed table. Both `of these guide bars, however, extendbeyond the conveyor chains 25 through 'a lining station A and on into the closing machine I2. The forward or closing machine 'sections are supported on a feed table 33 of the closing machine, brackets 34 being used'for holding the guides on the table.

AThe can 2| advanced bythe chains25 as it approaches their inner ends, that is, as it moves over the sprockets 21, is pushed off of the chains and onto a continuously revolving can carrier disc 4 I. The can is stillretained withinxthe guide bars 29, 3|.

At the lining station A the can now'carried on the disc 4I passes along part 42 of the guide rails 29, 3| Aand is thereupon shifted from its straight line of travel and is caused 'to move along the path of a reversed curve, this, being the form of the rail part 42. The forward end of, the curved section merges into the straight forward end sections of the guide rails 29, 3| on the closing machine table 33. It is during this passage of the can along the curved guided rail section 42 that its top flange 22 is engaged by a lining pad I5 moving around the spider I1 and upon such engagement lining material onthe pad is transferred to the flange of the can. v i

The disc 4I is formed on the upper end of a vertically disposed sleeve 45A (Fig; l) which is journaled in a bearingy 46formedin the frame II. The disc 4I is enlarged as a hub 41 where it merges into the sleeve 45 and it is this hub that rests upon he top of the frame bearing and by means of which the disc, sleeve, etc., are retained at the proper level. The disc 4I with its sleeve 45 is continuously rotated in any suitable manner as by suitable driving power' applied to a lower gear 48 keyed on the lower.` endVv of the sleeve and locked in` place by a. lock nut 49 threadedly secured thereto.

The spider I1 with the lining. .pads I5 are rotated in unison withthe dise 4I and for this purpose a sleeve 5I is located inside of the disc sleeve 45 andextends above and below the disck sleeve. Sleeve 45 is provided with a longitudinally disposed feather'vvay 52 which extends from near the bottom sleeve end up into the disc/hub 41'. A feather 53 is carried in this featherway and has slight movement in al corresponding featherway 5&3 cut llongitudinally kof the sleeve 5|. Thisconstruction insures uniforrnrotation ofthe two sleeves While permitting vertical movement of the inner sleeve 5| Within thedisc sleeve 45.

The spider I1 is carried on and is keyed-to the upper end of the sleeve 5| and inasmuch as this spider carries the liningjpads and parts associated therewith, the position ofthe sleeveSI within the disc sleeve determines the height of the taller can is to be lined it is merely necessary to secured to .the frame I I.

raise the sleeve 5Il within the disc sleeve 45 in order to bring the lining pads I5 to a higher level. An easy adjustment of the spider and parts carried thereby is provided forand consideration will now be given to this feature, reference being had to Fig. 1.

A vertical stationary shaft 55 extends through the sleeve 5I and projects both above and below it. This shaft is threaded at its lower end at 55 and carries a collar 51 pinned in fixed position to the shaft on which the sleeve 5I rests. The weight of the sleeve, the Weight of spider and parts carried thereby are supported at all times upon this collar. y

The shaft 55 is held in a bracket 6I which is This bracket is formed With spaced bearings 62 in which the lower threaded section 56 of the shaft 55 is loosely positioned. A hand wheel 63, internally threaded. threadedly engages the shaft end 56 intermediate thebearings 62 and this hand wheel carries the weight of the shaft and through it the weight of the spider I1, sleeve 5| and the lining units. The shaft end 56 is cut longitudinally with a featherway 64 and a feather 65 is preferably located in each bearing 62. This construction al lows for Vertical movement of the shaft 55 but prevents its rotation. Turning of the handwheel 63 on the shaft 55'raises or lowers theV shaft and the lining parts carried thereby as desired def The upper end of the stationary shaft 55 is reduced in diameter to form a vstem 1I and a shoulder at the junction line between the two diameters. This stem carries a split collar 12 which rests on the shoulder and an enlarged lower section of the collar is located in afrecess 131 formed in the upper end of the central hub part of the spider I1. A ring 14 is secured by screw 15 to the spider and in cooperation with the recess forms a movable joint at this place. The collar 13 is keyed to the stem 1| and so is also held stationary While the spider I1 and the ring 14 rotate With the sleeve 5|. v

The stem 1| also carriesa gear 16 which rests upon the collar 13 and which is also keyed to the stem. A ring cam 11 is mounted upon the stem 'II above the gear 16 and this cam is also held in stationary position, being also keyed to the stern. A washer 1S and a look nut 19 mounted on the upper end of the stem holds collar, gear and cam together as a single stationaryunit. 5

The spider I1 carries three vertically disposed hubs 8| (Figs. 1 and`3) which are equally spaced around the periphery of lthespider upper wall and one of the rods I6 is carried in each hub. A gear 82 is formed as an integral part of and is located at the top of a vertically disposed sleeve 83 and eachof these sleeves is journaledfor rotation Within one of the spider hubs BI. vEach sleeve 83 is also threaded at its lower end and a lock nut 84, located just below the hub rbearing 8|', is threaded on the sleeve and this holds Asleeve and gear against any vertical movement Within` the bearing.

Three idler gears 85 are carried on the tcp wall. of the spider I1 and each gear isfpinned to the upper end of a short vertical shaft 86 which is journaled in a boss 81 formedin the spider wall. The lower end of each shaft 86 extends below fits Jooss i851 and a ycollar l438 pinned' Tte the shaft maintains the flatter 1in r-otatable positi'on Within -itshub Eachiidlergear meshes 'with the sta-- ll-,ionary -gear 'F16 and as v-the fspider rotates the 'gears 85 fare icaused `vto imove I'around -f'th'e center stationary gear and yare thereby rotated.

The iloWerfsur-face of the pad "95 is the yele- -ment -of the lining'unt which "engages with lthe -fiange 22 of the :can '2=| `during the' lining operation.

In -onecycle fof vmovement of a lining pad |-'5, ythat is, during a single rotation Aof the spider y"Il, the pad is 'caused -to pass over a `supply roller operating in a fixed 'tank-or reservoir and is falso brought `into alignment withthe canas it'passes along the curved rail section 42 ofthe guide yrails I`29, 31| which has just been described. Each 'lining pad has a raised andla lowered position and Vwhen a pad passes over the applying roller it is in its 'upper position. lWhen passing fthrough the lining station it is-cause'd to descend into 'lining position.

Thisfdi'fferencelin liorizontalposition is brought about-by araising andflowerin'gfdfthefrod |56 associated with Ia lining unit. -For tliis :purpose each -rod |5 at Iits upper 'end fand `above ithe gear '32 carries a block L10| (Figs. lL1 'and 3*) which is -loose- 1y mounted lon the "rod being held -in place by spaced collars |02 pinned to the rod. fEach block 10| projects inwardly 'toward the center 'of the shaft -55 -a'nd 'isform'ed with a curved face -|0`3 which slides 'along the outer periphery of -the stationary cam -of the block |-0`| Aprevents rotation ofthe block 'with the rotating `rod 16.

The lining material which is liquid or at least 'semi-liquid is retained within a reservoir indilcated generally lby the numeral (Fig. 2). This reservoir `is heldin a stationary position 'above the Adisc 4l| and is offset or at one side l'of the path of travel of Vthecans Ipassing along the guide "rails '29, 33|. lThe reservoir 'com- `prises a Itank H72 (see also Figs. v1 and *61) land y f "this'tank 1is supported in ian adjustable position |l21| 4lifts a film of lining fcompound' rom fthe.

The liquid lining material is vlifted from Areservoir vand is :applied 'to the lower `Surface .of the absorbent pad 96 by an applying 'roller '|21 (Figs. l and 2). This roller is carried on ia horizontal shaft |22 journaled in louter :and inner bearings |23 formed in the tank, theinner bearing being located on the tank projection |20. 'Ihe applying roller is continuously rotated with lits shaft |22 and for this purpose the out'erfend of the'shaft extendsloeyond the outer bearing rl 23.

The shaft |22 carries a gear |24 .whichmeshes with a similar gear |25 pinned to the upper :end of a vertical 'shaft |25. Shaft |25 is .journaled adjacent its upper end in a boss |21 formed in the reservoir tank frame H2 and centrally :of the bosses I1. The shaft |26 at its lower end extends into a gear `|28 which is elongated fat sits lower end in an integral sleeve section |29. This `sleeve is journaled in a bearing |3| formedin the bracket lframe H8 (see also Figl). l

When the reservoir is raised or :lowered as previously described the shaftf |-26 =is correspondingly raised or lowered and at such time slides inside of the gear |28. The Ashaft |26 `carries a `feather |33 which slides vlin Va featherway formed longitudinally of lthe :shaft and by means of this construction the rotating cooperation between gear and shaft is maintained and insures unit movement of shaft and gear.

reservoir and applies it to each absorbent pad `96 when a pad passes over the roller. Such a passage and the transfer of the lining material ,onto the pad surface is accompanied by a wiping action as the pad moves along its circular path across the upper face of the roller and also as the rotating pad is moving on its own axis. This assures' a more even distribution of the lining material upon the lining pad. In addition to the wiping and distributing feature provision is also made for regulating the thickness of the film left on lthe applying roller |2|.

A scraper blade |5| is adjustably secured (Figs. 2 and 5) on a bridge member |52 which extends across the tank I2 having projections |53 which .rest onthe oppositeside walls of the tank `where they` are secured in position. The blade |5| is "slotted at |54 and the enlarged head of a Screw |55 engages within the slot |54. There are two of these screws |55 and two corresponding slots |54 in the blade'.

Each screw |55 is threadedly secured in a central rib |56 formed in the bridge |52 and rotation of a screw within its slot gives a fine adjustment to the blade |5| by drawing that side of the blade 'forward or back. An exact thickness of film of absorbent pad 96 by a repeated piling up of maten rial from one cycle to another provision is made for scraping the entire lower surface of the pad clean at each cycle of operation and just before anew charge is put on by the roller I2 I. For this purpose a 'scraper |6| is secured to the rib |55 and its upper edge is vertically adjustable by means of which it may be placed to drag across the lower part of the pad as it moves over the reservoir and before it comes into engagement with the applying roller |2|. This scrapes the pad clean each time and presents a new or clean A pair of pointed adjusting screws |62 are threadedly secured in the bridge |52 at the back part of the reservoir the tapered ends of these screws engaging a tapered lower edge of the scraper-bladel |6|. By moving the screws in, the blade is pushed up on the rib |55 and a very line After it vhas been properly located the blade is clamped in Vits adpusted position by screws 63 which pass through slots formed in the blade and which threadedly engaged within the rib |56. A lock nut |64 threadedly engaging each of the adjusting screws |62 may be used for holding these screws in their adjusted positions.

Reference has already been made to the fact vthat a can after it has-received the lining material on its flange 22 continues its advancement been found satisfactory for this purpose there is illustrated in the drawings a chain conveyor |1| which operates in suitable grooves formed in the seaming table 33. This chain carries a series of pivoted can propelling arms |12. Each arm is rocked on its pivotal mounting on the chain through' Athe action of a cam track |13 along |16 journaled. in suitable bearings formed in the closing machine table33.

The shaft |16 (Figs. land 7) may receive rotation ldirectly from the drive gear 48 through a train of ygears enclosed within the housing lThe shaft |16 carries a gear |11 which meshes with an idler gear |18 rotating on a stud |19 secured inthe frame Gear |18 also meshes with a second idler gear |8| loosely `mounted on a stud |82 also carried in the frame The gear |8| meshes with the drivegear 48 and in this manner the conveyor chain |1`| .is synchronized with the lining machine and properly advances an arm |12 so that it will engage behind the can at the lining station A and will slide it off of the disc 4| and thence convey it along the closing machine'table 33 while the can is confined in its path by the guide rails 29, 3|. l .A

` The 'lined can is in thisV manner advanced to a seeming station B (Figs. 1 and 2) wherefit may be placed upon a lift plunger or other suitable support |8| which lifts it into seaming position within a seaming head |83'in the usual manner. During the seaming operationthe arm |12 is backed off relative tothe advancing chain |1| by being pivoted on its mounting through the action of the cam roller |14 and the cam track |13. The seaming operation thus takes place without stopping thev conveyor chain |1|. This construction is well known and it is believed further description is unnecessary for the purpose of the present in,- vention. It will be understood that a can end or cover is brought into the seaming station in the regular way, this being a feature of the closing machine itself.

Itis thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changesmay be made in the form, construction and arrangement of the parts without departing fromthe spirit and scope of the invention or sacricingall of its material advantages, the form hereinbeforedescribed` being lmerely a preferred embodiment thereof.
